How to Be a Dark Hero’s Daughter

Duke Kallen de Lewelton is bloodthirsty and ruthless when it comes to killing criminals, but a total sucker when it comes to his new daughter! Peasant girl Lae learns this herself when a fateful run-in with the duke results in her adoption into the Lewelton home. Armed with a sharp mind and the knowledge from her past life, Lae makes the perfect addition to the family’s quest to quell injustice. But as the mysteries of the capital’s underbelly rise to the surface, will she and her new family withstand the return of a true criminal mastermind?

The MC transmigrated into a novel and became an extra from the novel. The novel is a murder thriller and the main character is a serial killer. He kills criminals with black magic making him a dark hero (think of him as Dexter or batman with dark magic). She (MC) doesn’t have any death flags since she’s a background extra but she was a homeless girl of all things in such a dangerous novel. Somehow our MC saves the male lead and to thank her, he adopts her. “Become my daughter.” The richest, most powerful, and handsome duke commands her to be his child. The MC is freaked out since she knows he’s a cold-blooded killer. Can she survive such a maniac? Yet he dotes on her and constantly says ‘my daughter is the cutest’! He wants to get master artists to draw her and gather poets to describe her adorableness. The duke also has a son. And because the apple doesn’t fall far from the tree, he also dotes on her. In this way, a beggar became a little princess. She also got used to people getting killed. However, there was still one problem. Our MC has turned sixteen and is wondering as a lady, will she have an arranged marriage? The whole house atmosphere quickly turns awkward. She realizes, perhaps they want her to stay here forever? Can she escape such a strange house? Everyone is so attached to her!
